Hello, I have been dedicated to learning how to effectively use my Omron CJ2M PLC in conjunction with an ABB ACS 355 VFD and Fena-01 adapter. I understand the concept of controlling the VFD through a fieldbus adapter via a communication network, as opposed to using digital inputs like DI1-6. However, I am struggling to determine which parameters of the VFD correlate to specific addresses on the PLC. Specifically, I am interested in being able to adjust the motor frequency on the touchscreen interface instead of directly on the VFD. Can you advise on which PLC address to utilize for setting the frequency - should it be in the D area, W area, or another location? Thank you for your assistance.
To ensure compatibility between the Omron CJ2M and the ABB ACS 335 (FENA-01 adapter), it is crucial to identify the communication protocol(s) they both support. Based on my research, both devices are compatible with the EtherNet/IP protocol, which is ODVA's CIP (Common Industrial Protocol) over Ethernet. Configuring the ABB drive is essential as it offers various EtherNet/IP profiles, each determining the parameters exposed to EtherNet/IP. Refer to the FENA-01 documentation for detailed information (starting on page 120) to select the appropriate profile to meet your requirements. For the Omron PLC, setting up implicit messaging is necessary. Download the ABB drive's EDS file and register it in the Omron PLC settings. Useful videos demonstrating the setup process using Omron PLC and configuring Ethernet/IP communication are available for reference.
Hey there! It sounds like you're really diving deep into your Omron and ABB setup—exciting stuff! For controlling the motor frequency via your PLC, you'll want to look into the specific communication protocol used between your Omron CJ2M and the ABB ACS 355, typically Modbus or another fieldbus type. Generally, frequency settings are mapped to certain addresses in the VFD's parameter list, so consulting the ACS 355 manual is essential. Usually, the frequency setpoint can be associated with a specific register, often found in the D area of the PLC for processed data. If you’re looking to adjust it via your touchscreen, you’ll need to ensure that the mapped parameters align correctly in your PLC program. Good luck, and feel free to share your progress!
